L mal working position, the valve proper being 15 is a screw by means of which the disk 14 v arranged to move vertically when the cock is is secured in place on the end of the valve 13. 35 opened or closed. When the ball-cock is in its normal position,

The said body O consists of a horicasing. The valve 13 is fit-ted in its housing 9o 4o zontal portion 2 of the form shown, which so as to move freely therein, and thus the terminates in an enlarged or rounded portion whole force exerted by the device which op- 3, forminga substantially globe-shaped chamerates the said valve may be exerted to press ber, with an opening at top or upper portion the valve tightly against its seat. When the thereof having a screw-cap 4, the removal of valve is being closed, a certain amount of the 45 which permits ready access to the interior of uid passing through the cock will be forced the device. It will be seen that there is a didownwardly between the valve and its housrect passage through this globe-shaped chaming and might spray out over the edges of the ber, so that the interior valve-fittings may be tank if the tank used were a small one. To placed in position in and withdrawn from prevent this spraying, Iprovideahood (shown roc 5o this said direct passage veryreadily in amanat 10, Figs. l and 2) which is designed to ner which will presently appear. The cap t catch any water which may strike the cam 21 and fly off therefrom and return it downwardly into the tank.

18 is a discharge-pipe through which the iiuid passing through the valve discharges into the receptacle in which the ball (not shown) operates. The discharge-pipe 18 is screwed into an opening formed at 19in a downwardly-projecting integral portion of the body C, which forms an outflow-chamber. The said discharge-pipe opening is connected with the valve-cham ber by means of the opening or passage 20. When, therefore, the valve is open, fluid passes from the pipe connection A, through the horizontal body portion 2, into the rounded portion 3 of the casing, thence through the openings 8 in the tube 7, through the valve-opening, thence through the passage 20, and out through discharge-pipe 18.

For the purpose of operating the valve 13 I provide a cam 21. which is pivoted on a screw-pin 22. The pin 22 preferably is provided with a flat head 23, by means of which it may be turned readily by the thumb and finger. The screw 22 passes through lugs or projections at the opposite sides of the downwardly-projecting portion 17 of the casing. The cam 2l is provided with a socket 24, in which the end of a rod or stem (not shown) is secured, the ball or float being at the other end of said rod or stem. The plunger or valve 13 rests upon the cam-surface 21, as shown, and, as will be clear, the position of the ball or float relatively to the pivot-pin 22 will determine the position of the valve or plunger 13 relatively to its seat and the enlargement or restriction of the valve-opening. By removing the cap 4 the tube 7, the lower end of which forms the seat of the valve, may be readily removed from Within the casing 3. By removing the fulcrum-pin 22 the cam 21 may be withdrawn and the plunger or valve 13 removed. Thus all the parts of the device which are likely to need repair and renewal may be very readily removed and replaced Without disturbing the body or casing C. When the valve and valve-seat are removed, the interior of the shell or casing may be easily cleaned. The arrangement of the valve 13 to move vertically and of the actuating-cam 21 in a substantially horizontal position increases the efliciencyof the power exerted by the ioat to close the valve. The space within the portion 3 of the shell around the tube or seat 7, as also within the upper portion of the said tube 7, has a cushioning eect, the pressure being distributed throughout the fluid in said spaces, with the result of lessening the wear at the valve-seat and rendering it possible to close the Valve and maintain it in its closed position with less force than would otherwise require to be exerted.

The modification shown, Figs. 3and 4, consists chieiiyin making the portion 26, to which the cam 21 is pivoted, separable, which permits the said portion to be turned and the ball located in any desired position relatively to the valve. The said portion is exteriorly threaded, as shown at 25, Fig. 4, to form a plug or stuing-nut 26. The plug has an axial hole therethrough, in which the valvestexn 27 is placed. At opposite sides of the plug are formed downwardly-projecting lugs 28, between which the cam 21 is pivoted by means of a pin 22, which is of the same shape and performs the same function as the pin 22, heretofore described. The lugs 28 are provided at their lower ends with two sets of holes or bearings 30 and 31 for the pin 22. This is for convenience in assembling the parts of the device and permits the cam 21 to be placed in operative position regardless of the point at which the plug 26 comes to a full bearing. For example, if in Figs. 3 and 4 it were desirable or necessary to give the plug 26 an extra half-turn the hole 31 would then be in position to receive the pin 22, on which the cam 21 waspivoted. This arrangement also facilitates the setting of the iioat in any given position relatively to the fixed parts of the valve.

lVhile in the accompanying drawings the ball-cock is shown in its normal position for a top supply for a tank, it will be clear` that it is equally applicable for a bottom supply when that is desired.

What I claim is- In a ball-cock, the combination with a casing having an integral enlargement at one end to form a substantially globeshaped chamber, said enlargement having a direct passage therethrough; a depending portion 19 integral with said casing and forming an outflow-chamber, said outIiow-chamber communicating with said direct passage through port 20; a tubular shell mounted in the upper end of said direct passage, said shell being provided with inlet-openings intermediate its ends and having a Valve-seat formed at its lower end; a screw-cap closing the upper end of said direct passage and said tubular shell and serving to hold said shell in place; ajreciprocating valve mounted in the lower end of said direct passage beneath the valve-seat formed at the lower end of said tubular shell; and a ball-cock head to actuate said valve.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID W. GORMAN.
